如果是后台上传文件:

setting配置：

STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static'),
os.path.join(BASE_DIR, "media"),
]
# Django用户上传的都叫media文件
MEDIA_URL = "/media/"
# media配置，用户上传的文件都默认放在这个文件夹下
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

model的配置：
img = models.FileField(upload_to="img/",verbose_name="图片")

接收任何文件的前端代码：

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="post" action="/upload/" enctype="multipart/form-data" target="ifm1">

<input type="file" name="file" id="file"/>

<input type="button" value="提交" onclick="upload()"/>
</form>
<br>
<br>
<br>
<br>
<div>显示图片
<img id="images">
</div>
<br>
<br>
<br>
<br>
<div>显示路径
<a href="" id=" rel="external nofollow" imagess">链接</a>
</div>

</div>
<br>
<br>
<br>
<br>
<div>
{# href="/static/img/TC代码.txt" rel="external nofollow" #}
<a id="up"> 下载文件</a>
</div>

<script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js"></script>

<script>
function upload() {
var formData = new FormData();
var file = document.getElementById('file').files[0];
formData.append("file", file);
$.ajax({
url: "upload/",
type: "post",
data: formData,
dataType: "json",
cache: false, //上传文件无需缓存
processData: false,//用于对data参数进行序列化处理这里必须false
contentType: false, //必须*/
success: function (data) {
console.log("22", data);
$("#images").attr("src", data.image)
$("#imagess").attr("href", data.image)

}
});
}
$("#up").on("click", function () {
$.ajax({
url: "http://127.0.0.1:8000/down/",
type: "get",
data: {},
success: function (data) {
var $a = $('<a></a>');

$a.attr("href", "http://127.0.0.1:8000/down/");
$("body").append($a);
$a[0].click();
$a.remove();
}

})

});
</script>
</body>
</html>

增加任何文件的后端接口代码：

from rest_framework.views import APIView
from django.shortcuts import render, redirect, HttpResponse
from dal import models
from django.http import JsonResponse

class ImageShow(APIView):

def post(self, request):
name = str(request.data.get("name"))
message = {}

img_url = "/static/img/{}".format(name)

obj = models.Car.objects.filter(img_url=img_url).first()
if obj :

message['code'] = 200
message['message'] = img_url # 返还路径
return JsonResponse(message)

下载文件后端：

from django.utils.http import urlquote
from rest_framework.views import APIView
from django.shortcuts import render, redirect, HttpResponse
from dal import models
from django.http import JsonResponse, FileResponse, StreamingHttpResponse

class fileShow(APIView):

def get(self, request):
message = {}
file = open('media/img/TC代码.txt','rb') # 字符串替换成文件
print("file",file.name)
# file_names = file.name.split('/')[-1]
# print("file_names",file_names)

response = FileResponse(file)
response['Content-Type'] = 'application/octet-stream'

response['Content-Disposition'] = "attachment;filename={}".format(urlquote("TC代码.txt")) # 字符串替换成下载文件
print(response)
return response
